The purpose of this design project was to investigate the effect of various design and operating parameters on the thermal efficiency, net work output per unit mass, and back work ratio of a regenerative Brayton cycle. Specifically, these parameters include the pressure ratio, TminTmax ratio, regenerator effectiveness, and compressor and turbine efficiencies, assuming the working fluid to be air at 100kPa and 300K at the compressor inlet. Model calculations are presented…show more content…

Due to their low overall thermal efficiencies, gas turbines initially had limited uses. As time has passed, many renovations have been implemented to the gas turbine cycle to make it more efficient. Some modifications include: increasing the turbine inlet temperatures, increasing the efficiencies of turbo machinery components, and adding modifications to the basic cycle. In contrast to the ideal cycle, the actual cycle undergoes unavoidable pressure drops during the heat addition and heat rejection processes. In addition, the actual work input to the compressor is always more than the output and the actual work output of the turbine is less than the work input due to irreversibility. These relationships are displayed in the figures below:

Four other common modifications to the simple ideal and actual Brayton cycles include: 1) Regeneration 2) Reheat 3) Intercooling 4) Regeneration with Reheat and Intercooling
The only methods amongst these choices that improve the overall thermal efficiency of the ideal Brayton cycle are those that utilize regeneration. However, each of these four improvements also increase the initial cost of building the equipment as well as the maintenance cost for the cycle. Thus, deciding which power cycle to build depends on economics as much as it depends on engineering.

TI CYCLES: NEW PRODUCT STRATEGY
INTRODUCTION
Company Overview
TI Cycles was established by the Murugappa Group in the year 1949, in collaboration with Tube Investments, UK. The first Hercules bicycle rolled out in 1951. Three more brands were added to the portfolio - Phillips in 1959, BSA in 1964 and Montra in 2011. Today, TI Cycles is the leader in the ‘specials’ segment. It has a network of around 1,500 primary dealers and 10,000 secondary dealers.
TI Cycles has the capacity to…

Life Cycle Analysis For Brick
1 Materials are very important in construction industry because with the combination of different material, we can create a very strong and unique building form. There are many type of material that commonly used in the construction industry, for example the glass, woods, bricks, stones, marble, concretes and etc. Brick is one of the most commonly used materials in Malaysia, because almost every house in housing area was built by bricks. From this essay I want to give…

Labor is an important factor of production for all firms.
Business information is not perfect at Wal-Mart Stores: economic experts are not dismayed or surprised with the unemployment rates at the stores. Employees at Wal-Mart stores are likely to be affected by frictional unemployment. This occurs at a result of everyday changes in the company's economic structure, which is likely to lead to the death of the firm. Employees…

• Analyse the elements of the ‘Intelligence Cycle’. What are its core strengths and weaknesses?
Before I begin to analyse the elements of the Intelligence Cycle, I must begin with the definition of ‘Intelligence’.
Throughout my research, it became apparent that the acceptance for an accurate definition of ‘Intelligence’ is still an issue to date. One reason could be because experts tend to view ‘intelligence’ through their own specialty, and would be fair to say that this…

Life Cycle Cost Analysis
Life cycle cost analysis (LCCA) is a process of evaluating the costs that can be identified and quantified, to include all factors like acquisition, sustaining, maintaining and final disposition of the item, that can have an impact on the whole system cost during its life span. (Blanchard…

Life-cycle cost analysis (LCCA) is a method for assessing the total cost of facility ownership. It takes into account all costs of acquiring, owning, and disposing of a building or building system. LCCA is especially useful when project alternatives that fulfill the same performance requirements, but differ with respect to initial costs and operating costs, have to be compared in order to select the one that maximizes net savings. For example, LCCA will help determine whether the incorporation of…

Life Cycle Analysis
"A buildings environmental impact extends from global factors, such as ozone depletion, to the quality of the environment inside the property. These impacts arise from decisions made at all stages of the buildings life, including materials manufacture, site selection, design, construction, occupation and ultimately demolition."
